Description

Technical Field

[0001] The utility model relates to the technical field of cable supports, and more specifically, to a rail transit communication cable support structure. Background Art

[0002] Rail transit communication cables are an important part of the communication system and an important medium for subway data transmission and wireless signal coverage. They are like the "nerve veins" of the rail transit system, closely connecting various parts to achieve rapid transmission and interaction of information.

[0003] When laying communication cables in subway sections, it is usually necessary to use a supporting structure to support and fix the cables. Therefore, choosing a safe and reliable cable support structure is of great significance to ensure the safe and efficient operation of the subway.

[0004] The existing cable support structure usually uses plastic clamps and load-bearing steel wire ropes for support and fixation. Due to the closed and humid characteristics of subway tunnel sections, plastic clamps and steel wire ropes are very easy to decay and damage. In addition, there are many cases of leaky coaxial cables being hoisted in special shield sections (such as open-cut sections, section openings, sharp bends, and the junction of the main line and the entry and exit lines). At this stage, they are only fixed by installing load-bearing steel wire ropes at the hoisting location, which has a high risk of intrusion. In view of this, we propose a new type of rail transit communication cable support structure. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model places multiple cables between a fixing block 1 and a fixing block 2, fastens the multiple cables by using a dividing strip 1 and a dividing strip 2, pushes the fixing block 2 so that the fixing block 1 and the fixing block 2 clamp the cables, and then passes through the insertion hole 2 from top to bottom through a latch bolt and extends into the insertion hole 1, until the bottom of the latch bolt is fixed by a nut after passing through the insertion hole 1, so that the fixing block 2 is fixed on the support frame, the cables are clamped and fixed, and it is difficult for them to fall off.

[0028] The bottom of the support frame 103 is connected to an oblique support 104, and the bottom of the oblique support 104 is connected to the side wall of the base plate 101;

[0029] The support frame 103 is provided with a plurality of sockets 105 from top to bottom, and a slide groove 106 is provided on the side wall of the support frame 103, and the slide grooves 106 are symmetrically distributed on both sides of the support frame 103.

Two slide columns 205 matching the slide groove 106 are connected to the side wall of the support plate 204, and two slide columns 205 of the same structure are connected to the other symmetrical side wall of the support plate 204. A sliding column 205, a dividing strip 1 301 and a dividing strip 2 303 are connected to the top surface of the support plate 204, the dividing strip 1 301 and the dividing strip 2 303 are flexible strip structures, a card block 1 302 is arranged on the top of the dividing strip 1 301, a card block 2 304 is arranged on the top of the dividing strip 2 303, a card column 1 305 matching the card block 1 302 is arranged on the top of the fixed block 1 201, and a card column 2 306 matching the card block 2 304 is arranged on the top of the fixed block 202;

[0030] In the embodiment of the utility model, the base plate 101 is fixed to the wall of the subway tunnel by bolts, and the multi-strand cable is placed between the fixing block 1 201 and the fixing block 2 202.
